addDetector() ¶ public static

addDetector(string $name, callable|array $callable): void

Add a new detector to the list of detectors that a request can use. There are several different formats and types of detectors that can be set.

Callback detectors

Callback detectors allow you to provide a callable to handle the check. The callback will receive the request object as its only parameter.

addDetector('custom', function ($request) { //Return a boolean });
addDetector('custom', ['SomeClass', 'somemethod']);

Environment value comparison

An environment value comparison, compares a value fetched from env() to a known value the environment value is equality checked against the provided value.

Pattern value comparison

Pattern value comparison allows you to compare a value fetched from env() to a regular expression.

addDetector('iphone', ['env' => 'HTTP_USER_AGENT', 'pattern' => '/iPhone/i']);

Option based comparison

Option based comparisons use a list of options to create a regular expression. Subsequent calls to add an already defined options detector will merge the options.

Request parameter detectors

Allows for custom detectors on the request parameters.

Provides a read/write accessor for $this->data. Allows you to use a syntax similar to Cake\Model\Datasource\Session for reading post data.

Reading values.

$request->data('Post.title');

When reading values you will get null for keys/values that do not exist.

Writing values

$request->data('Post.title', 'New post!');

You can write to any value, even paths/keys that do not exist, and the arrays will be created for you.

Returns

mixed|$this

Parameters

string $key: The key you want to read/write from/to.
string|null $value optional: Value to set. Default null.
string|null $default optional: Default value when trying to retrieve an environment variable's value that does not exist. The value parameter must be null.

getAttribute() ¶ public

getAttribute(string $name, mixed $default = null): mixed

Read an attribute from the request, or get the default

Retrieves a single derived request attribute as described in getAttributes(). If the attribute has not been previously set, returns the default value as provided.

This method obviates the need for a hasAttribute() method, as it allows specifying a default value to return if the attribute is not found.

Parameters

string $name: The attribute name.
mixed $default optional: The default value if the attribute has not been set.

Returns

mixed

getAttributes() ¶ public

getAttributes(): array

string $default optional: The default value if the cookie is not set.

Returns

null|array|string

getCookieCollection() ¶ public

getCookieCollection(): Cake\Http\Cookie\CookieCollection

Get a cookie collection based on the request's cookies

The CookieCollection lets you interact with request cookies using \Cake\Http\Cookie\Cookie objects and can make converting request cookies into response cookies easier.

This method will create a new cookie collection each time it is called. This is an optimization that allows fewer objects to be allocated until the more complex CookieCollection is needed. In general you should prefer getCookie() and getCookieParams() over this method. Using a CookieCollection is ideal if your cookies contain complex JSON encoded data.

Returns

Cake\Http\Cookie\CookieCollection

getCookieParams() ¶ public

getCookieParams(): array

Get all the cookie data from the request.

Retrieves cookies sent by the client to the server.

The data MUST be compatible with the structure of the $_COOKIE superglobal.

Provides a safe accessor for request data. Allows you to use Hash::get() compatible paths.

Reading values.

// get all data
$request->getData();

// Read a specific field.
$request->getData('Post.title');

// With a default value.
$request->getData('Post.not there', 'default value');

When reading values you will get null for keys/values that do not exist.

Parameters

string|null $name optional: Dot separated name of the value to read. Or null to read all data.
mixed $default optional: The default data.

Returns

null|string|array

Returns

string|null

withMethod() ¶ public

withMethod(string $method): static

Update the request method and get a new instance.

While HTTP method names are typically all uppercase characters, HTTP method names are case-sensitive and thus implementations SHOULD NOT modify the given string.

Parameters

string $method: The HTTP method to use.

Returns

static

withParsedBody() ¶ public

withParsedBody(null|array|object $data): static

Update the parsed body and get a new instance.

These MAY be injected during instantiation.

If the request Content-Type is either application/x-www-form-urlencoded or multipart/form-data, and the request method is POST, use this method ONLY to inject the contents of $_POST.

The data IS NOT REQUIRED to come from $_POST, but MUST be the results of deserializing the request body content. Deserialization/parsing returns structured data, and, as such, this method ONLY accepts arrays or objects, or a null value if nothing was available to parse.

As an example, if content negotiation determines that the request data is a JSON payload, this method could be used to create a request instance with the deserialized parameters.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated body parameters.

Parameters

null|array|object $data: The deserialized body data. This will typically be in an array or object.

Returns

static

withProtocolVersion() ¶ public

Parameters

string $version: HTTP protocol version

Returns

static

withQueryParams() ¶ public

withQueryParams(array $query): static

Update the query string data and get a new instance.

These values SHOULD remain immutable over the course of the incoming request. They MAY be injected during instantiation, such as from PHP's $_GET superglobal, or MAY be derived from some other value such as the URI. In cases where the arguments are parsed from the URI, the data MUST be compatible with what PHP's parse_str() would return for purposes of how duplicate query parameters are handled, and how nested sets are handled.

Setting query string arguments MUST NOT change the URI stored by the request, nor the values in the server params.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that has the updated query string arguments.

Parameters

array $query: The query string data to use

Returns

static

string $target: The request target.

Returns

static

static

Throws

InvalidArgumentException
